COP2_001 Sustained Operational Provision of Historical Climate Forcings for CMIP and Wider Applications

ECMWF, as the Entrusted Entity for both Copernicus Climate Change Service (C3S) and Copernicus Atmosphere Monitoring Service (CAMS), invites tenders for the development and implementation of the components required for a transition to a sustained mode of operation in the provision of historical climate forcings data for the Coupled Model Intercomparison Project (CMIP) and other uses.C3S and CAMS aim to support the climate forcings community with the transition to a sustained mode of operation. A key element of this goal is to support the needs of non-CMIP users that require near-current historical forcing data, with appropriate long-term support for dataset versions deemed fit for specific purposes.

This Invitation to Tender (ITT) is a first step towards this vision, and will establish an operational infrastructure layer supporting sustained, high-quality, regularly extended climate forcing datasets for the historical to near-present period, while also scoping and producing a longer-term vision for future historical forcings provision. This will ensure that the infrastructure, quality control, documentation, and regular extension of existing forcing datasets become continuous activities and complement the well-established forcings research activities which support CMIP.ECMWF intends to award a single Framework Agreement, with a maximum duration of 27 months, which shall be implemented via a single multi-annual Service Contract, expected to commence at the beginning of Quarter 4 2026.Portal instructions:Some of the ITT documents are accessible under the ‘Attachments’ box at bottom right of this page.

The full set of ITT documents which are provided inside the response questionnaire are only accessible by registering an interest in this opportunity (see the 'Expression of interest window' at top right). Questions / clarifications concerning this ITT must be submitted via the Messaging area of the ITT, which can be accessed through the My Activities page of the Portal once you have logged-in and registered your interest in this opportunity.
